It was named after Russian astronomer Matvei Gusev (1826–1866) in 1976..More recently, satellite images showed the trails of dust devils on Gusev's floor.. The Spirit rover later photographed dust devils from the ground, and likely owes much of its longevity to dust devils cleaning its solar panels..Becoming a naturalized U.S. citizen in April 1991, Chawla applied for the NASA Astronaut Corps...
